4 reasons some people even cheat on happy relationships – by a psychologist

One of the most disturbing betrayals – when someone in a seemingly happy relationship loses. Conventional wisdom suggests that people cheat because something is missing: passion is faded, communication is broken or dissatisfaction has taken root. But the truth is, many issues are not due to dissatisfaction, but for much more complex psychological reasons.

Some people deceive despite loveing ​​their partner. They can deeply appreciate their relationships and still find themselves drawn to infidelity. This contradiction can be confusing to the betrayed partner and even the person who deceived himself. But why does this happen? What hidden forces push someone to risk something they feed?

Here are four deeper psychological factors after why some people cheat – even in happy relationships.

1. The seduction of innovation and tracking dopamine

Romantic love is deeply linked to the dopaminergic reward system of the brain, the same nervous network that directs motivation, pleasure and reinforcement. In the early stages of a relationship, this system is very active, flooding the brain with dopamine – the neurotransmitter responsible for the intoxicating rush of withdrawal. Everyone’s look, touch, and late night conversation feels electric, strengthening the desire to follow and focus on a specific partner.

But over time, this initial high fades. Research using FMRI scans has shown that romantic transitions of love from a dopamine-driven motivation system to a more stable, bonding state, backed by oxytocin and vasopressin-hormones that deepen trust and bonding. While this shift is natural and necessary for sustainable engagement, some people struggle with the loss of excitement of the early phase.

For those who want constant stimulation, an affair can feel like a quick way to restore that beloved feeling of love. This is not to say that they want to leave their relationships – many people who still deceive still feel deeply connected to their partner. But the temptation of an exciting experience, driven by danger, can overcome their best judgment.

Here’s what you can do-instead of searching for innovation outside of the relationship, you can actively revive your dopamine-driven excitement. The same reward routes that create initial withdrawals can be stimulated through new common experiences, such as surprising one another, traveling spontaneously, exploring new hobbies together, or deepening intimacy in fresh ways. Romantic love does not have to lose its intensity over time – it simply requires deliberate effort to keep the brain engaged and excited within the relationship.

2. Fear of deep weakness

Paradoxically, some people cheat not because they feel detached, but because they feel very connected. For individuals with avoiding bonding tendencies, deep emotional intimacy can feel overwhelming, causing fear of loss of autonomy, becoming very dependent or exposing the weaknesses they have long protected.

Those who grew up in environments where love was conditional, unstable or even harmful may have learned that proximity leads to pain. As a result, true intimacy – where they are fully seen and emotionally invested – can feel disturbing.

Fraud, then, becomes an unconscious way to create distance, allowing them to recover a sense of emotional control. The affair is not necessarily for the other person – it is about buffering by the weakness of deep engagement. A new, less strong connection can feel “safer” than the emotional exposure required in a long -term relationship.

A 2013 study published Psychological science and social personality Provides penetration on how to navigate this fear and wish the connection gap. The study highlights two main findings:

  • Building trust Over time, it reduces the avoidance of bonding, making the commitment feel more secure for those who fight intimacy.
  • Supporting personal growth of a partner And independence reduces the anxiety of bonding, helping emotional proximity feel less restrictive.

True security in the relationship does not come from avoiding dependence, but from knowing that love and personal autonomy can coexist.

3. Identity crisis – ‘I’m still me?’

Long-term relationships bring two lives together-routine intertwined, change identities and advantages mix. While this can promote a deep connection, it can also lead to an identity crisis, especially for those who strongly associate self -esteem with independence, spontaneity or adventure.

Over time, some may think they have lost contact with the version of themselves once – the person who was single, careless or explorer. They can begin to see themselves more as a partner than as an individual, leading to a sense of stagnation.

INVESTIGATION In the model of self-extension suggests that people have a fundamental motive to expand their sense of themselves-deepening relationships or following new, stimulating and challenging experiences. When this innate movement for self-extermination is unfulfilled within the current relationship, individuals can seek it somewhere else-including infidelity.

Fraud, in this case, is not necessarily to reject a relationship, but to restore a lost sense of oneself. The affair becomes a wrong attempt at self-exploration, a way to capture freedom, desire or excitement that seems to be missing in everyday life. However, the research suggests that self-extermination does not seek to get out of the relationship-can bloom inside it.

Instead of seeking individuality through infidelity, cultivate a personal growth within the relationship. Engage in hobbies that are just for you, keep friendships out of the partnership and create solo experiences that strengthen your independence. Thesis for a fulfilling relationship is not the sacrifice of autonomy – it is ensuring that love and personal growth coexist than to compete.

4. Self-esteem unconscious

Some people deceive not because they are unhappy, but because they do not believe they deserve happiness. When someone has grown up in chaotic or unstable emotional environments, a healthy and safe relationship can feel foreign, even worrying. Instead of embracing stability, they consciously anticipate its end and take the parade actions to disrupt it.

A 2010 study of connectivity development and emotional abuse suggests that individuals who experience rejection, control or childhood hostility often develop unsafe connecting styles, which damage emotional adjustment, create negative self-perceptions and interfere with the ability to keep intimacy. If love was unpredictable in early life, they can integrate the belief that happiness is temporary, love always comes with betrayal, or stability is very good to extend.

As a result, when they find themselves in a fulfilling relationship, they may feel disoriented or anxious, waiting for something to go wrong. In this case, in this case, there is an unconscious defense mechanism – a way to reaffirm their inner belief that relationships always end in pain. By sabotaging their happiness, they recover a sense of control over a result they already fear.

Breaking this cycle requires consciousness and healing from the wounds of the connection past. If you find yourself leaving people when things are going well, ask yourself:

  • “Do I struggle to trust happiness in the relationship?”
  • “Do I assume things will be separated even when there is no evidence?”
  • “Are I repeating patterns from past relationships or childhood?”

Understanding why after infidelity does not justify it, but it offers a way to healing. If a betrayal has already happened, the most important question is not just “why did this happen?” But “How do we grow up from here?”

Are you sure in your relationship, or do you want excitement, seeing other partners as the best way to find it? do The degree of satisfaction of the relationship to discover.
